Retinol
Also known as: Vitamin A, Retinoids, Retinal, Retinaldehyde, Retinyl Palmitate
Overview
Retinol is a form of vitamin A and one of the most extensively studied anti-aging ingredients in skincare. It accelerates cell turnover, stimulates collagen production, and reduces the appearance of fine lines, wrinkles, and hyperpigmentation.
How Retinol Works
Retinol is converted to retinoic acid in the skin, where it binds to retinoid receptors in skin cells. This activates genes involved in cell differentiation and proliferation, increases collagen synthesis in the dermis, and normalises keratinisation — reducing clogged pores and improving skin texture.
Benefits
- • Reduces fine lines and wrinkles by stimulating collagen production
- • Improves skin texture and reduces pore appearance
- • Fades hyperpigmentation and evens skin tone
- • Helps treat acne by regulating sebum production and cell turnover
- • Increases skin firmness and elasticity over time
Side Effects & Cautions
- • Initial irritation, dryness, and peeling (retinisation period)
- • Increased sun sensitivity — SPF is essential
- • Not recommended during pregnancy or breastfeeding
- • Can worsen rosacea or eczema if used too aggressively
Who Should Use Retinol
Adults concerned with signs of aging, uneven skin tone, acne, or overall skin texture improvement. Best started in your late 20s as a preventative measure.
Who Should Avoid It
Pregnant or breastfeeding women, those with severe eczema or rosacea (without dermatologist guidance), and anyone not willing to commit to daily SPF use.

Topical retinoids significantly improve photodamaged skin, including wrinkles, roughness, and hyperpigmentation.
0.1% retinol applied for 12 weeks significantly improved wrinkles and global photodamage.
Retinoids are a cornerstone of acne therapy, normalising follicular keratinisation and reducing inflammation.
